Already have an Alaska/Atmos cash Companion Fare code? Use the companion taxes shown at checkout—not the advertised $23 minimum—to decide whether to use it.
Alaska’s announcement describes a $99 base fare plus taxes and fees “from $23.” That means a starting point, not a guaranteed tax bill or an all-in companion price. The word “from” is doing actual work.

What the wrong tax input does
This hypothetical eligible booking is not a live quote or guaranteed saving. Suppose the primary ticket costs $420 including taxes, the companion base is $99, and checkout shows $68 in companion taxes and fees.
Hypothetical trip math
Leave $23 in the taxes field and the calculated total becomes $542, with apparent savings of $298. That overstates savings by $45—the difference between $68 and $23. Spreadsheet optimism is still optimism.
Keep the inputs separate
Use the calculator at https://practicalrewards.com/calculators/alaska-companion-fare.html with your own code’s base fare and checkout taxes. Account or code terms can differ; do not force $99 into every calculation.
The primary-ticket field already includes its taxes. Enter only companion taxes and fees in the taxes field—not the full $167 companion total on top of the $99 base.
The catch: this calculator estimates using your inputs; it does not fetch live fares, validate your code, or book tickets. Compare alternatives with similar fare conditions, bags, seats and schedules.
Practical verdict
Use this approach for an existing cash Companion Fare code; skip it for a points-based companion award. Keep the annual fee separate from the use-this-code decision, then assess card costs and the full benefits package when judging whether to keep the card. Replace example taxes with checkout taxes before trusting the savings.
